@asvishnyakov Alexander, could you make code review please

[asvishnyakov]

1. User must not be able to add multiple prices with the same number of min. quantity
2. You must check 'delete' permission on price deletion (look at api controller) and 'pricing:read' in item-prices.tpl.html
3. (note sure, @tatarincev confirm please) api/products/{productId}/{catalogId}/pricesWidget → api/catalog/{catalogId}/products/{productId}/prices or api/pricing/{catalogId}/{productId}/prices
4. Do not use inline styles

1, 2 and 4 items from code review were implemented in last commits. 3rd item not applicable for this task i suppose

I updated Pricing module on demo-vc to preview changes.

Done incorrectly, there shouldn't be a drop down for pricing. There should be "Add Price" button in the toolbar and no pricelist dropdown. Look at the description of 3 cases given in VirtoCommerce/vc-platform#1115

Another batch of the changes is available on the demovc-admin-dev for preview:

1. fix validation data in grid
2. display name of currency in price list selector
3. empty (N/A) initial list price instead 0
4. disable hiding editable columns List price and Min. quantity
